Description
Technical Field
The utility model relates to a gear for motor, in particular to from fixed gear.
Background
The existing assembly process of a motor shaft and a gear is as follows: assembling the azimuth and pitch master gear; trial assembling the azimuth and pitch motor, sleeving a gear on a motor shaft, and adjusting the meshing degree of the gear with the main gear and the auxiliary gear by adding or subtracting a gasket so as to determine the position of a matched pin hole; the gear, the motor and the gasket are disassembled and then matched, a drilling machine is used for matching pin holes, when the drilling machine is used for drilling, flat tongs are needed to clamp a boss of the gear, and a riveting plane of the gear is adjusted once and again, so that a drill bit is perpendicular to the riveting plane; after the pin hole is punched, the adjusting gasket is detached; and assembling the motor and the gear on the scanner, and upsetting and preventing the pin from loosening.
The pinhole has a great degree of difficulty on the motor shaft that the shaft diameter is little, and the axle is just little itself, and the intensity of motor shaft can reduce after the pinhole has been processed, and clearance fit also can make the precision of gear reduce.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at providing a from fixed gear, through the fixed mode of self in order to solve the motor shaft and punch and the problem of turning stationary plane.
The technical scheme is as follows: the utility model relates to a self-fixing gear, which comprises a body; a connecting hole is formed in the center of the body, a connecting sleeve in a hollow conical shape is integrally formed at the edge of the connecting hole of the body, and the connecting sleeve is composed of a plurality of arc-shaped connecting sheets arranged at intervals; the connecting sleeve is sleeved on the motor shaft, the outer wall of the connecting sleeve is connected with a fixing block of a fixing hole, the fixing hole is in a hollow conical shape, the fixing block is embedded on the outer wall of the connecting sheet through the fixing hole, the fixing block is in interference connection with the connecting sheet, and the fixing block enables the connecting sheet to be in interference fit with the motor shaft.
Further, the radial supporting wall and the fixed block of body all open the pinhole, and the radial supporting wall and the fixed block of body are fixed through pinhole cooperation round pin axle between.
Furthermore, the fixed block integrated into one piece has annular lug, and annular lug is used for cooperating with the connection piece, and annular lug is in order to increase the length of fixed connection piece of fixed block.
Further, the fixed block is circular, and the external diameter of fixed block is the same with the internal diameter of the radial support wall of body.
Furthermore, an annular bulge is integrally formed between the radial supporting wall of the body and the connecting sleeve.
Has the advantages that: compared with the prior art, the utility model: the motor shaft does not need to punch and turn the fixed surface so as to realize the fixation with the gear, and the mounting screw is directly screwed, so that the motor shaft is simple, convenient and quick, the position of the gear is determined without adjusting the gasket, the trouble of punching a pin hole and riveting a pin by a pier is avoided, the mounting difficulty is reduced, and the mounting power is improved.

Detailed Description
As shown in fig. 1, a self-fixing gear includes a body 1; a connecting hole is formed in the center position of the body 1, a connecting sleeve 2 in a hollow conical shape is integrally formed at the edge of the connecting hole of the body 1, and the connecting sleeve 2 is composed of a plurality of arc-shaped connecting sheets arranged at intervals; the connecting sleeve 2 is sleeved on the motor shaft, the outer wall of the connecting sleeve 2 is connected with a fixing block 4 of the fixing hole 3, the fixing hole 3 is in a hollow conical shape, the fixing block 4 is embedded on the outer wall of the connecting sheet through the fixing hole 3, the fixing block 4 is in interference connection with the connecting sheet, and the fixing block 4 enables the connecting sheet to be in interference fit with the motor shaft.
The motor shaft passes from gear body 1 and connection piece, and motor shaft and connecting hole and connection piece are interference fit, then the connection piece embedding is to the fixed orifices 3 of fixed block 4, and connection piece and fixed block 4 also are interference fit, and fixed block 4 further makes adapter sleeve 2 compress tightly the motor shaft, has realized the fixed of motor shaft and gear.
In order to avoid the relative sliding of the fixing block 4 relative to the connecting sleeve 2, the body 1 and the fixing block 4 need to be fixed together, so that pin holes 5 are formed in the radial supporting wall of the body 1 and the fixing block 4, and the radial supporting wall of the body 1 and the fixing block 4 are fixed through the pin holes 5 in a matched mode.
In order to enable the connecting piece of the connecting sleeve 2 to be completely positioned in the fixing block 4, the fixing block 4 is integrally formed with an annular convex block 6, the annular convex block 6 is used for being matched with the connecting piece, and the length of the connecting piece fixed by the fixing block 4 is increased by the annular convex block 6.
In order to maintain the synchronism between the fixed block 4 and the gear body 1, the fixed block 4 is circular, and the outer diameter of the fixed block 4 is the same as the inner diameter of the radial support wall of the body 1.
In order to avoid damaging the radial supporting wall of the body 1 when the connecting piece is machined, a distance needs to be reserved between the connecting piece and the gear, and therefore an annular protrusion 7 is integrally formed between the radial supporting wall of the body 1 and the connecting sleeve 2.
